Product Introduction

Overview

The LM74800QDRRRQ1, produced by Texas Instruments, is an ideal diode controller designed for automotive applications. This device is part of the LM7480x-Q1 family, which includes the LM74800-Q1 and LM74801-Q1 variants. It is AEC-Q100 qualified, ensuring it meets stringent automotive standards. The LM74800QDRRRQ1 operates over a wide input voltage range of 3 V to 65 V, making it suitable for protecting and controlling 12-V and 24-V automotive battery-powered Electronic Control Units (ECUs). It features reverse input protection down to –65 V and drives external back-to-back N-Channel MOSFETs in common drain and common source configurations to emulate an ideal diode rectifier with power path ON/OFF control and overvoltage protection.
